This press upon it due to its ownweight causes the uncoated side of the thread to become coated and thus the thread has become fully coated on both its sides with the material composing cylinders D and D guide M serving as a means to reverse the waxed side of the thread and to guide the unwaxed side of the thread to engage with the second waxing cylinder D and such office of M being its main function. The thread now passes through guide P and then is engaged by guide R a part of the winding machine which directs the thread T onto cone S.

This invention, therefore, provides, a suitable means to fully coat threadson both of its sides while they are'being wound, with any substance the thread maybe required to be coated with. The guide M also provides asmooth path for the running thread T, and

the thread is likewise aided. by having the plates F turned down a little on their ends.

Two such cylinder plates are necessary for this invention and are set on pins 0 and are free to turn on same through hole G in cap Z fitted on to tube E which has alittle cap similar to cap Z with a hole size E set in at the bottom of tube E in the plane of plate F.

Fig. 5 shows the pins C thread a little up their length to point J and such pins are set into frames .A in their relative positions as shown in Fig. 1 by having two nuts H hold each pin in place through holes in angles frame A. c

I claim as my invention:

1. A thread waxing device comprising an angle frame, two pins set one into each arm of said angle frame, which pins are each adapted to receive a Wax cylinder moving axially and circularly-thereon, and interposed between said pins at the bend in the frame, a means to reverse the side of the thread first exposed for waxing, and means to guide the unwaxe'd' side of the thread to engage with the second of said wax cylinders.

2. A thread waxing device comprising an angle frame, two pins set one into each arm of said angle frame, which pins are each adapted to receive rotatable mounted spindle plates, and each of which spindle plates are adapted to receive a cylinder of wax moving axially and circularlythereon, and

interposed between saidpins at the bend in the frame, a'means to reverse the side of the thread waxed by'the firstof said cylinders of wax and means to gulde the unwaxed side of the thread to engage with the second of said.

cylinders of wax.

In testimony whereof, I aflix my signature.
